dacoontz- loading jets really isn't difficult. the number of reloadings per case is directly related to how hot you load them. i use hs-6 for my normal play load at the starting amount. it is available on the hodgdon website. i do use a magnum primer also.it is plenty fast to use at 100yds. the best part is the cases last for a good long time. you will have a loose primer pocket before anyting else. then you can use a couple more times if you use cci primers. your new boxes of 50 cases i might not use,but anything fired is fair game. make sure you size them down far enough so they don't have to be pushed into the cylinder. enjoy your jet. they are a hoot.
